It is He who made the earth submissive to you; therefore walk in its tracts, and eat of His provision; to Him is the Uprising. 15 Are ye secure that He who is in the heaven will not sink the earth with you and then it should quake? 16 Or are you secure of those in the heaven that He should not send down upon you a punishment? Then shall you know how was My warning. 17 And indeed those before them belied (the Messengers of Allah), then how terrible was My denial (punishment)? 18 Have they not seen birds above them spreading and closing their wings, with none holding them except the Merciful One? He oversees everything. 19 Who is there to defend you like an army, besides the Lord of Mercy? Those who deny the truth are in deception. 20 Who is he that can provide for you if He should withhold His provision? Nay, but they continue to be in pride, and (they) flee (from the truth). 21 Is he who walks without seeing on his face, more rightly guided, or he who (sees and) walks on a Straight Way (i.e. Islamic Monotheism). 22 Say, "It is He who brought you into being, and made ears and eyes and hearts for you, yet you are seldom grateful." 23 Say: He it is Who multiplieth you in the earth, and unto Whom ye will be gathered. 24 And they say: when will this promise be fulfilled, if ye say sooth? 25 Say: The knowledge (thereof is only with Allah and I am only a plain warner. 26 At length, when they see it close at hand, grieved will be the faces of the Unbelievers, and it will be said (to them): "This is (the promise fulfilled), which ye were calling for!" 27 Say thou: bethink ye if Allah destroy me and those with me; or have mercy on us, who will protect the infidels from a torment afflictive? 28 Say: 'He is the Merciful. In Him we believe and in Him we put all our trust. Indeed, you shall soon know who is in clear error' 29 Say, "Have you not thought that if your water was to dry up, who would bring you water from the spring?" 30
